PROTECTING UNDERGROUND WIRES AND PlPES.

SPECIFICATION forming part of Letters Patent No. 351,913, dated November 2, 1886.

Application tiled January 4, 188'2. Serial No. 49.394.

To ctZZ whom/'it may concern:

Be it known that I, WORCESTER HADDooK,

of the city of Cincinnati, in the count-y of'I-Iamf ic means for transmitting and protecting electric wires and gas and water pipes underground in such a manner that they may bc easily reached, and to provide means for retaining said wires and pipes in position.

Referring to the drawings forming part of this specication, Figure lis a transverse section across the main tube or covering and its accompaninients and showing the various wires and pipes in position. Fig. 2 is a sectional view representing one side of the tube or envelope and its accompaniments, the section being taken at the line :r a: of Fig. l, and looking toward the side which is at the right hand in said figure. Figs. 8 and et are detail views showing the diii'erent forms of insulators which I employ. Fig. 5 isa plan view showing the manner of turning a corner, and also avoiding the catch-basins of the sewer at the street corner. Fig. 6 is a sectional elevation of the arrangement shown in Fig. 5, looking toward the top of said figure, and also showing the method oi' crossing a street. Fig. 7 is a transverse section of the tube which leads to- Ward the right hand of Fig. 6.

The outer covering or tube, X, is composed of the side plates, c a at w3 at, the bottom plate, a5, and the top plate, a, preferably made of iron. The meeting edges of `these plates are provided with flanges b, through which bolts are passed 4 to secure the various plates together. The

side plates, a a', preferably extend perpendicularly downward from the curb A. The plate a preferably extends perpendicularly downwardly for a short distance,and then obliquel y .i5 downward towardthe middle of the street.

The plate at preferably extends obliquely upward from the bottom plate, ct, to a point beneath the lower edge of the plate ai', and the plate a3 extends perpendicularly between and 5o to the plates a2 and at. The plate c' preferalNo model.)

bly has an angle plate, b', which extends obliquel y downward across an edge of said plate b', being slightly removed from the plate c5, leaving an opening through which water may pass the bottom plate,c5, the edgeol' this plate 5 resting on lugs b", cast on the bottom plate, ai".

The top plate, c, preferably extends across the top ofthe tube, one edge being provided with the flange c, which rests in a channel, c, in the top edge of the plate a2, and the other 6o edge resting on top of the plate a andk against the curb A.r Joists A extend across the top ofthe tube, and are secured at either end to brackets B B on the plates a and a2, and upon these ioists rests the top plate, a, the upper surface ofwhich is shaped to form the gutter to carry oii` the water from the street. A piece of rubber or other elastic material, b5, is interposed between the meeting ends of the various plates a, (see Fig. 2,) to allow for ex- 7o pansion and contraction of said plates, and yet form a tight joint to prevent water from running into the tube to any considerable extent. This elastic piece is placed on one of the joists A", and is retained thereon between the upwardly-extending flanges b* on thejoists. The bottom plate, a5, is made concave, and is provided at intervals with outlets A2, through which any water which may run into the tube is conveyed to the sewer. lVithin this tube so formed the electric wires and gas and water pipes are placed.

At intervals along the bottom of the tube are placed the brackets D, upon which the gas and water mains D D2 arelaid. The brackets D are provided with shoes d, for preventing the brackets from tilting. One of these shoes rests in the angle formed at the junction ofthe side' plate, a', and the oblique plate b', the other shoe, d, at the other end ofthe bracket resting against the oblique side plate, at. These brackets are not bolted to the tube X, as it is desirable that they should be longitudinally Aadjustable in the' tube X to avoid the joints in the pipes. The shoes, however, hold g5 the brackets in position and prevent them from tilting. The upper edges of these brackets are provided with notches, in which the pipes are laid. A foot, d, is formed on the under side of the bracket D, which foot rests upon the roo ridge di on the bottom plate, a". d d" represent branches ofthe mains D D?, thesebranches passing through the sides of the tube X.

Above the pipes and at one side of the tube Xthe electric wires are supported, as shown in Fig. 1. Upright posts E (see Figs. 1 and 2) are placed at intervals along the length of the tube, the upper ends of the posts being bolted to the underside of the joists A. These posts, preferably, do not extend entirely to the bot tom ofthe tube, but rest upon the upper end of oblique posts E, the lower ends of which latter posts are bolted to the oblique side plate, d. rlhe upper end of thepost Eand the lower end of the post E are bolted together, as shown in Fig. 1, and an upright shoe or brace, E2, extends from this joint down to the bottom of the tube, the lowerend of this brace resting on the ridge di on the bottom plate, a5. The ad vantage oi' this construction is that it allows either of the posts to be removed without 1naterially interfering with the others. rlhis is necessary to allow free access to the pipes or wires in cases o f repairs or of putting in new lines of cable or wire. The electric wires traversing this tube must be insulated in any appropriate manner, andlhaveshown two methods of accomplishing this and of supporting the wires. ln the upper part of the tube I have shown wires e, each one of which is insulated independently of the others, and below these wires I have shown several bundles of wires contained in common insulators ethat is, several wires contained `in one cable or general insulator, but preferably insulated from each other.

Extending from the side plates, a3 a", to the oblique post E are the brackets F, one end of said brackets resting on lugs on the side plates and the other end resting against the oblique post E'. These brackets F may be bolted to the side plates and the post E, if desired, or the ends may be provided with'iianges projecting from the sides of the brackets, which will prevent the brackets from turning. On these brackets F are laid the bundles e of insulated wires, the brackets being preferably notched on their upper edges to receive said bundles.

Above the bundles e' are the bars ci, extending from the side plates of the tube X to the post E. These bars in cross-section are shaped as shown in Fig. 3, and between these bars are placed the insulators en, made of glass or other non-conducting substance. These insulators are preferably made in sections, so that the various wires may be placed in position without the necessity of drawing the entire wire through the insulator, as would be necessary were the insulators made in one piece.

rIwo forms of insulators are shown in Figs. 3 and 4, which may be employed. The one shown in Fig. 3 is provided with a nuinberof teeth, et, around which the wires are turned, as shown in the upper part of Fie'. 3. rlhis retains the wire in position, preventing it from slipping. rljhe under side of these insulators is provided with a notch, c'", which lits on the bar e2, as shown in Fig. 3. A separate plate, e, of glass or other non-conducting substance, is placed on top of the teeth el after the wires have been placed in position, preventing them from becoming detached from the insulators.

Another form of insulator is shown in Fig. 4. This insulator is made in two halves, each half being provided with a notch to fit on the bars e, and also with another notch, which, when the two halves are placed together, forms an opening, el, through which the wires c pass. Each of these insulators may, if desired, be provided with two openings, el, as shown in the. second row in Fig. 1. rilhe object of this construction of the insulators is to permit the various wires to be stretched the entire length p of the tube before being attached to the insulators. \Vooden strips or bars h are bolted or otherwise attached to the various brackets and posts, around which the wires c arc conducted and to which they are secured, to prevent rhcln from coming in contact with any of the metal in or belonging to the tube X, or with eac-h other, as they are conducted from or into the tube.

The kind of insulated cables or wires and .their inode of insulation and their precise location within the tube X may be varied as desired. Figs. 5 and 6 show the manner of conducting the tube around a catch-basin at the st-reet corner and also or' crossing a street. Fig. 5 shows a pipe, G, passing around the catclrbasin, and illustrating how it may be conducted in either direction. As the tubeX crosses the street it is preferably lowered, as shown in Fig. 6, tlre purpose of this being to place the tube low enough to be out of the way of street repairs. Another and important object of this lowering of the tube as it crosses the street is to permit underground cable railways to be constructed in the street without interfering with the tube. there the tube X crosses the street it may, if desired, be made double, as shown in Fig. 7.

lVhen it is desired to inspect any of the wires or pipes in the tube, one of the top plates, Y a, is lift-ed., when a man can descend into the tube, and the space H being free from wires or pipes, he may go from one end of the tube to the other, if he so desires.

If preferred, cross piecesor jointsl may be laid across the space H, one end resting on a lug on the side plate and the other on the pipe D', and upon these joists a plank, J, may be laid, upon which the man may walk; but this plank may be left out and the man may then walk on the pipes.
